Take 10 minutes to think about who you spent time with today.
"The first tool for experiencing more moments of love entails simply reflecting, at the end of each day, on the three longest social interactions you've had that day, and asking yourself how 'connected' and 'in tune' you felt with the people with whom you spent your time. These people could be family, friends, coworkers or completely new acquaintances, and it doesn't matter whether the same person shows up in more than one interaction. [In studies,] reflecting on social connection appeared to penetrate the body to affect enduring heart rhythms. We speculate that the daily question serves as a subtle cue that reminds people that each of their social interactions is indeed an opportunity for something more than just an exchange of goods and information."
